The WSJ has a good description of the princelings here, including the problems they’re causing in a country where most people still can’t even dream of lifestyles so opulent:

One evening early this year, a red Ferrari pulled up at the U.S. ambassador’s residence in Beijing, and the son of one of China’s top leaders stepped out, dressed in a tuxedo.

Bo Guagua, 23, was expected. He had a dinner appointment with a daughter of the then-ambassador, Jon Huntsman.

An uproar ensued, and the general’s son has now been sent to a police correctional facility for a year, state media report.

Last year, Chinese learned via the Internet that the son of a former vice president of the country—and the grandson of a former Red Army commander—had purchased a $32.4 million harbor-front mansion in Australia. He applied for a permit to tear down the century-old mansion and to build a new villa, featuring two swimming pools connected by a waterfall.
